"I would like to confirm to you that the Miss Delaware Teen USA pageant has received a resignation letter from Miss King's attorney," pageant spokeswoman Dara Busch wrote in an e-mail this morning.

A porn website posted a sex video Monday featuring a woman who looks and sounds like King. The site claims it is the teen pageant winner. King, contacted Monday, said she was aware of it but denied it was her.

"Absolutely not," she said. "It is not."

Of the porn site's claim, she said, "There are comments saying this; however, it's not comments that are true."

King, 18, who was crowned Miss Delaware Teen USA last year, declined to provide her lawyer's name Monday. However, pageant officials identified him as J. Gregory Hannigan of Hagerstown, Md. He did not immediately return messages.

An email sent Monday night seeking comment from the website that distributed the video was not answered.

Busch, who is executive vice president and managing director with Rubenstein Public Relations, said the runner-up will take King's position.

According to the Miss Delaware Teen USA website, Hailey Lawler of the Newark, Del., area is the runner-up. She could not be reached for comment.

Miss Delaware Teen USA is run by the New York-based Miss Universe Organization. This is not the first time issues have arisen with the organization involving a Delaware contestant. In 2005, Sheena Benton was allowed to remain Miss Delaware USA and compete in the nationally televised pageant after it was learned she had pleaded guilty for drunken driving in 2004.

And this is certainly not the first time there has been a sex scandal involving a pageant contestant. In 1984, Vanessa Williams gave up her Miss America title after nude photos of her surfaced. The Miss America pageant is not associated with the Miss Universe Organization.

The video, a recording running just over 5 minutes, starts with an interview on what appears to be a hotel bed. The woman does not give her name. But when the man, who is not shown or identified, interviewing her asks when she turned 18, she says "about three months ago. March."

King is 18 now, and her birthday is in March, according to the Miss Delaware Teen USA website.

The interviewer then asks her what made her want to do her first adult video.

"I thought it'd be fun, and it sounded like I needed the money," the woman says. "So I just decided to do it."

The interviewer asks more questions, including if she has a boyfriend, when was the last time she had sex and how old she was the first time she had sex. The woman laughs a little as she answers.

That portion of the interview fades into another set of questions where the interviewer asks her about being a "Miss. A Miss Teen?"

When the woman acts reluctant to talk about it, he says "I'm not going to say the state or anything. ... You did beauty pageants?"

"I've done them, yes," she responds.

While King won the Miss Delaware Teen USA title in November, at the time this video was shot - this past summer - she was the reigning Miss Teen Delaware International 2012.

The interviewer then asks her if she has told anyone about doing the video, to which the woman replies: "It's not a big secret. But I didn't tell anybody specifically what I was doing."

Following the interview, the woman and a man, whose face is never seen, perform several different sex acts.
